Abstract: PURPOSE: To obtain a laminated body which can stably and repeatedly cause reversible change between a uniform colorless transparent state and enough white opaque state with temp. change without showing no dependence on visual angles by using a soln. in which an acrylamide water-soluble polymer is uniformly dissolved. CONSTITUTION: Such a soln. 2 that the water-soluble polymer aggregates with temp. increase to change into a white and light-scattering state and to decrease the transmittance for light is laminated with a substrate l which is at least partly transparent to enable direct observation of the soln. 2. The soln. 2 consists of 100 pts.wt. of water, 0.1-100 pts.wt. of acrylamide water-soluble polymer and 0.01-20 pts.wt. of ionic polymer. The acrylamide water-soluble polymer can uniformly dissolve even at >=10wt.% high concn. and changes into a white and opaque state with temp. increase from 0 deg. to 100 deg.C. The sealing agent 3 is used to prevent vaporization of water, and a frame 4 is used to seal the soln. 2 body after laminated.

Title: Control system for throttle
Inventor: HONDA YOKO
IPC: F02D9/02
Filed: 1991-09-20
Abstract: PURPOSE:To reliably prevent overspeed revolution of the internal combustion engine from occurring by judging the abnormality of a motor in response to an intake pipe negative pressure signal of the internal combustion engine and disconnecting a negative pressure type clutch. CONSTITUTION:The opening of a throttle valve 2 is selectively adjusted either by an acceleration lever 3 operated by a driver or by an electric motor 4 driven by operation of a control system. At the time of a normal operation, an intake pipe negative pressure signal is introduced into a negative pressure type clutch 12 and, by this clutch 12, the motor 4 is connected to the throttle valve 2, the opening of which is thus adjusted by the operation of the motor 4. When the relation between the acceleration lever position and the throttle valve position falls out of a specified relation, i.e., when, for example, the motor is in abnormality, communication between windows 6d and 3d permits an atmospheric pressure signal to be introduced through operation of a control valve 42, thereby causing de-energization of an intake pipe negative pressure signal of a negative pressure introduction pipe 36 to cause disconnection of the negative pressure type clutch 12. This, in turn, permits the opening of the throttle valve 2 to be adjusted by the acceleration lever 3.

Title: Thyristor
Inventor: MIYASAKA YASUSHI
IPC: H01L29/74
Filed: 1991-09-24
Abstract: PURPOSE:To perform inflow of electrons into an emitter region for ignition through overall diffusion by stepwise varying the depth of emitter region formed in a base region and by increasing the lateral resistance of a base region with distance from a gate electrode or from the edge of an emitter region. CONSTITUTION:An n-type silicon substrate 1 of 240mum thickness is used to form a P<+> layer 2 on its one side face. Next, a P<+> region 3 is formed by selective impurity diffusion from a surface, and then a zone 43 remotest from the gate electrode of an n-emitter region is formed. Successively, a zone 42 shallower than it and a zone 41 closest to the gate electrode and shallowest are formed one after the other. This design develops a difference in the lateral resistance of a base region outside the emitter region, so that because of uniformity, current flowing concentratedly into the emitter region from a place near the edge of the gate electrode or the base region advances also to zones gradually increasing the lateral resistance of the emitter and becomes easy to flow overall. Thus, di/dt dielectric strength improves.
